Marine renewable energy sources such as wave and tidal power are poised to become an important part of the U.S. future clean energy mix. Recent Electric Power Research Institute (EPRI) and Georgia Institute of Technology studies have measured the annual technically recoverable energy from U.S. wave and tidal resources at 1,170 terawatt-hours (TWh) and 66 TWh respectively–a significant proportion of the 4,000 TWh of U.S. electricity demand. In practice, the realities of project development likely will result in a much smaller realized resource, but if 10 percent extraction can be reached, this would be equivalent to the output of 37 large fossil fuel plants.

Thorium reactors are usually considered not to be weapons proliferation risks, but this article from the Nuclear Threat Intitiative’s Global Security Newsletter suggests otherwise.  They report on an article appearing in Nature pointing out weapons proliferation risks connected to Thorium.  http://www.nti.rsvp1.com/gsn/article/bomb-risk-seen-alternative-atomic-fuel/?mgh=http%3A%2F%2Fwww.nti.org&mgf=1

From the Belfer Center at Harvard, August 2012, comes a very informative document clarifying the complex terminology used in discussing the nuclear situation in Iran.  This fascinating document also contains a condensed history and a wonderful map.  Read it all at:    http://belfercenter.hks.harvard.edu/files/Nuclear%20Iran%20A%20Glossary%20of%20Terms%20PolicyFocus121.pdf

This article, by Michael Richardson, on August 8, 2012, in Japan Times, questions whether the US should approve a new laser enrichment plant.  The argument is that laser enrichment could more easily be done secretly compared to centrifuge enrichment which requires large, industrial, not easily hidden, facilities.  The ability to secretly enrich uranium could enable secret production of highly enriched uranium for weapons.

This week marks the 67th anniversary of the nuclear bombings of Hiroshima and Nagasaki. On August 6, 1945, U.S. President Harry Truman informed the world that an atomic weapon had been detonated on the Japanese city of Hiroshima. Nicknamed Little Boy, the bomb with a power of over 20,000 tons of TNT destroyed most of Hiroshima, killing an estimated 130,000 people. Three days later on August 9, a second bomb nicknamed Fat Man was dropped on the Japanese city of Nagasaki destroying most of Nagasaki and killing roughly between 60,000 – 70,000 people. Six days after the bombing of Nagasaki, Japan surrendered, marking the end of World War II.  The destructive power of these nuclear weapons and the subsequent casualties of the Japanese have continued to prompt questions over whether the U.S. should have decided to use these weapons against Japan during World War II. Even 67 years after the event, the decision to drop the first atomic bomb continues to be widely debated.

The boom in natural gas production has undeniable benefits for the United States. But two policy analysts argue that embracing a monolithic energy future dominated by gas will mean the loss of a golden opportunity: Leveraging cheap, abundant gas to create a sustainable future based on renewable power.

What about Thorium?

August 13, 2012  FAS Roundup

There is four times as much thorium on Earth as there is uranium, and that less than 1 percent of uranium consists of U-235. In the past few years, there has been discussion in the United States, China and India regarding thorium power. What exactly is thorium power, and what are the pros and cons of it?
